I opted in to use JOINs, however; the sorting doesn't work This has the wrong sort order:

{

"q": "*",

"query_by": "_id",

"filter_by": "$balances(address:=...)",

"include_fields": "$balances(*) as balance",

"sort_by": "$balances(last_received:asc)",

"page": 1,

"per_page": 10

}

This has the correct sort order:

{

"q": "*",

"query_by": "_id",

"filter_by": "address:=...",

"sort_by": "last_received:asc",

"page": 1,

"per_page": 10

}
